Answer:
x- intercept = 6
Step-by-step explanation:
to find the x- intercept, let y = 0 in the equation and solve for x
2x - 3y = 12
2x - 3(0) = 12
2x - 0 = 12
2x = 12 ( divide both sides by 2 )
x = 6 ← is the x- intercept
Answer: There are 56 boys in the 10th grade
Step-by-step explanation:
Step 1
ratio of boys to girls in the 10th grade is 8 :13
Number of girls= 91
To find the number of boys, we first find the total number of boys and girls in the 10th grade
Step 2
Now the total ratio= 8 +13=21
Number of girls = ratio of girls/ total ratio x Total number of students
91=13/ 21 x Total number of students
Total number of students =21 x 91 / 13 =147
Step 3
Therefore Number of boys =ratio of boys/ total ratio x Total number of student
8/21 x 147=56
